Any PHP developers here have experience with Multi DB tenancy app with each tenant can have their our custom domain (tenant-one.com) then it will be pointed via CNAME to my app (tenant-one.myapp.com).

I have enough details for multi DB tenancy app using sub domains but for using custom tenant domain - not so much.

What are some good detailed tutorials on how to do this via CNAME?
What tips can you share about this? Thanks! 😃
